Specification of `Il'ietters Patent.

Original application led April 15, 1920, Serial No. 374,225. Divi-ded ani'thi's lapplication filetAu-gust 1 2, 1921. Serial 110.491,84. s Y l To all whom t may concer/m.'

Be it known that I', CHARLES,

a subject of the King of Great Britain, and

resident of the city of 'VVinnipeg, Province of Manitoba, Dominion of Canada, have invented certain new and useful Improvements in Hydrocarbon Burners, (for which I have filed application in Dominion of Canada April 15, 1920Serial No. 240,101;) and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates particularly to burners of the type disclosed in my pending ap.- plication Serial No. 374,225 of which this is a divisional part, and has for its object to provide a burner having a detachable chimney supporting attachment which may be removed when a chimney is not used. A further object is to provide a burner in which a more complete combustion will be obtained by providing the cap with ka plurality of air inlet openings arranged to produce a uniform distribution of air to the zone of combustion.

To this end the invention consists of the combination, construction and particular arrangement of the parts hereinafter described and pointed out in the claims.

For full comprehension, however, of my invention referencemust be had to the. accompanying drawings in 'which similar reference characters indicate the same parts, and wherein:

Figure 1 is a side elevation of my imr proved attachment in use; v

Figure 2 is a plan view thereof; and

Figure 3 is a `detail perspective view of the attachment alone. Y

In the construction illustrated in the drawings which is the preferred embodimentof my invention, the base is indicated at 2 and the cap at 2a. The lower edge of the latter terminates in a circumferential bead 3 and its dome is provided with the usual flame opening 4 and a plurality of air inlet openings. form andare located one on each side of the flame opening adjacent the top of the vcap as indicated at 5 and 6 respectively, and two on eachside of a plane perpendicular to the length of the flame opening and adjacent the bead 3 as indicated at 7, 8, 9 and 10 respectively. f Y' v The chimney supporting attachment is constructed and arranged .to be detachably coact with said fixed The latter are of semi-circular flat' ring 12 having Vdepending arms=13, 14

encircling the domeof the latter..

' The extreme lower ends of the arms 13 fins t .ratenteuApr 25, 1era.

mounted upon the burner and consists of Va E. ConApo,vv

and 14 are bent outwardly as at y16 to present inclined surfaces 17 Vwhich'enable the attachment t0 be sprung 'into' position by a slight downward pressure', eacharm adjacent the bent-out portion being onset-to provide a seat 18 from which the bead 3 will not become displaced in service. The arm 15 is of a different construction to that of the arms 13 and 14 in that it'isbent inwardly and upwardly as at 19 in U form,

the portion 19 having an offset 2O to receive the bead on the cap and being extended upwardly through an opening 21 in a radial extension 22. The portion of this extension which Yis located above the ring constitutes a spring jaw 23 which cooperates with two liXed jaws24 and 25 in gripping the usual bead 26 onthe lower end of theV lamp chim-v ney.` lThe `upper end of the spring jaw .is ,bent upwardly and outwardly to 'present an inclined surface 27 which is adapted to facilitate the positioning of the chimney. All

to receive the bead on fthe, chimney.

What I claim is as follows lof the jaws have concave gripping faces28 1. In a hydrocarbon burner the combinae. y'

, with the body thereof including abase portion and a cap mounted thereon said cap having a circumferential bead on ,its lower edge; of chimney supporting means independent of said capand detachablyy mounted lthereon said means consisting of a ring constructed and arranged toy encircle the upper endof the cap and having a plurality of fixed chimney retaining members upon its top; a resilient retaining member adaptedto members, and resilient means secured to the said ring and adapted to be sprung over the bead onsaid cap.` 2. In a hydrocarbon burner the combina-` tion with the body thereof including a base portion and a lcap mounted thereonsaid cap Y. having a circumferentialy bead on its lower-- edge; of chimney supporting meansindef pendent of said cap and adapted to -be detachablymounted thereon, said means consisting of a ring Aconstructed and arranged to encircle the dome of the cap and presenting a flat chimney 4supporting surface, said hydrocarbon burners Consisting of a ring having spaced fixed aws upon the top thereof and having al Vradial extension diamet rieally opposite said jaws, suoli' extension having an opening therein, and means for detachably securing the attachment upon a burner, said means Consisting of doWn- .vardly'projeoting resilient arms secured to the underside of said ring, one' 0i said arms "being turned upwardly insubstantially U- form and extended through said opening in the form of a jaw adapted to coact With the said lined jaws in gripping a Chimney.
